clear all;

%addpath('.....................\Multiprecision Computing Toolbox\')

syms A B C;

T=A+B*C;

mp.Digits(20);

a=37456795;

b=576879678;

c=7888797;

t=subs(T,{'A','B','C'},{a,b,c})

now I want a b c t are multiple precision

The 'subs' is part of Symbolic Math Toolbox and it requires input to be of 'sym' type.

To use it with multiprecision toolbox, please use explicit conversion function: mp2sym.

So that the code becomes:

digits(mp.Digits()); % make sure we use the same precision for 'sym' as in multiprecision toolbox.

....

t=subs(T,{'A','B','C'},{mp2sym(a),mp2sym(b),mp2sym(c)})

Reverse conversion can be done with sym2mp function.

Let me know if this fixes the issue.
